I'm looking to get a A/C water pump and like to hear from you guys. Thank you for your time.
Iwaki RD-30 is AC, correct? ;)

How do they dump to much heat? There very close to the basic design as DC water pumps. They just AC power.
none really for they dump to much heat into loop to make it worth while using one. IMO

I use the Eheim 1048 which is:
Pump output: 600 l/h 132 lmp. gal./h. 158 U.S. gal./h.
Delivery head: 1,50 m/wat.col. 4 ft. 11 in./wat.col.
Power consumption: 10 W
Hose connection (suction side): Ø13mm (1/2")
Hose connection (pressure side): Ø11mm (3/8")
Dimensions: 147 x 75 x 118 5.8 x 3 x 4.7 in.

OK, now compare that to a DDC 3.1 (weaker of the DDC's).
Maximum Discharge: ~ 116 GPH (440 LPH)
Maximum Head: 10.8 ft (3.3 m)
Nominal Power (@12 V): 8.3-12 W
Connection Size: 3/8" barbs
Dimensions: 2.4" x 2.4" x 1.5"
In water cooling, head pressure is the paramount factor in determining flow rate within the loop. This is due to the restrictions inherent in the blocks, rad(s), fittings and even the tubing.

The reason AC pumps dump more heat has to do with the type of motor. Brushless DC motors on like ddc pumps are one of the most efficient type of motors, so less wattage gets converted to heat.

what about magnetic water pumps? magnetic driven ones....

Mag drive pumps can be ac or dc, they just operate with a magnetic field that couples the motor and impeller. Because of this there are no shafts/seals, which means less friction, wear, contamination, and leakage. They are more epensive than mechanically coupled pumps and the magnetic coupling mechanism can not withstand higher torques. But in general a brushless dc mag pump should be more efficent than an ac mag pump.
